Where are we building?

At Openreach, we've recently announced an ambition to reach 25 million homes and businesses by December 2026, if the right investment conditions are in place.

In doing that, we’re determined to be as open and transparent about our build programmes as we can be. That's why we publish a range of details about our largest commercial programmes on our public website.  This includes the FTTP Fibre First Towns, Cities and Boroughs Build Programme, and the Market Towns and Villages Programme which covers locations within the most difficult to reach areas (the vast majority are in Area 3, as defined by Ofcom). 

In addition to these, our Fibre First Programme contains other smaller sub-programmes, for example BDUK, new sites, other demand-driven programs and smaller-scale infill which – due to their nature and scale – are not included in our publication. 

Our aim is to support the Government’s strategy, as set out in the Future Telecoms Infrastructure Review, to accelerate commercial full fibre network investment across the UK as well as giving our stakeholders (like council leaders, planners, MPs, our CP customers and the general public) a view of where and when we intend to build. 

This provides stakeholders with valuable information to make informed decisions on their FTTP investments and sales effort helping to encourage people to take up a full fibre service when it arrives. 

The lists of locations and exchanges are reviewed and agreed in advance of publication by our Fibre First Steering Group, to make sure all the published data is accurate and reflects our build plans at the time of publication.

We don’t intend to change plans or the list of exchanges, but building a new broadband network across the UK is a huge and complex engineering programme, so some changes may occur where we encounter unforeseen obstacles. For example, the start of any building work will be subject to us getting the right level of support from relevant local authorities, and our own operational capability and efficiency. This includes having access to multi-dwelling units, like apartment blocks. When it comes to the actual build, we might discover conditions on the ground which restrict the proportion of an exchange area that we can upgrade.

FTTP Fibre First Towns, Cities and Boroughs Build Programme

The above map currently shows Openreach’s FTTP plans for our Fibre First Towns, Cities and Boroughs and Market Towns and Villages Build Programme. It does not show FTTP deployment related to other programmes such as BDUK, new sites/retro new-sites, and other smaller scale programmes or infill.

Openreach has exercised its best efforts to ensure that the maps accurately reflects plans at the time of publication. Openreach will update the map on a rolling basis, including to reflect additional locations in later phases of network build or changes to existing plans which may become necessary due to unforeseen operational obstacles (particularly where build is yet to commence).

Our approach to publishing our Full Fibre build plans

  • Fibre First Towns, Cities and Boroughs Build Programme

    In 2018 we committed to DCMS that we would publish a 12 months forward-looking view of locations and the total number of exchanges we were planning to build within these locations in the next 24 months. We also committed to publish details of the specific exchanges where we're currently building FTTP, where it’s already been built, or where we were intending to start building within the next three months.

    The increased experience on the ground has given us ever greater confidence in the ability, level and accuracy to plan longer term and we're now in a position to publish details of new build tranches on a rolling basis.  These build tranches each cover our plans over approximately two years.

    Our approach to publishing our FTTP build plans includes loading on our website:

    • A list of towns and cities where we're already building FTTP as part of our towns and cities build programme, or where we intend to start building as part of our next build tranches (over approximately two years). For London and larger cities we also specify the boroughs.
    • The total number of exchanges – within the announced locations – where we intend to build scale FTTP as part of our next build tranche (over approximately two years), plus a list of previously announced locations.
    • The specific exchanges where we're currently building, where we've already built*, and where we intend to start building within the next three months. Details at an exchange level are shown only where Openreach expects that it will build in the greater majority of the relevant exchange.

    We update all of this information as appropriate every three months and you can view and download the list.

    Considering the published plans at exchange level, our intention is always to upgrade the greater majority of the exchange and we'll flag when any information for a location has changed. In the event that a town, borough or city is removed from the list, we'll always explain the reasons behind that decision.

  • Market Towns and Villages Build Programme

    We're also publishing the build plans for our Market Towns and Villages Programme. The vast majority of locations are in Ofcom's "Area 3".

    Following our recent announcement of our extended build ambition, in addition to the list of market towns and villages already published, we're now in the position to publish details of a new tranche of build covering our plans to reach an incremental 3m premises in market towns and villages (the vast majority of which are in Area 3) up to December 2026.

    This will contribute to the right investment conditions for Area 3 being in place. The data will provide further certainty to local authorities, investors and customers - and support the Government’s strategy to accelerate commercial investments in Full Fibre networks throughout the UK.

    Our approach to publishing our FTTP build plans for market towns and villages includes publishing on our website a list of all exhanges up to December 2026, including details of exchanges where we're currently building, where we've already built and where we intend to start building within the next three months.

    Openreach will keep this information updated on a rolling basis, including to reflect additional locations in later phases of network build or changes to existing plans which may become necessary due to unforeseen operational reasons (particularly where build is yet to commence).

    In the event that a location is removed from the list, we will always explain the reasons behind that decision.
